A data center GPU against a workstation card, one Hopper and one Ada Lovelace: 80 GB HBM2e against 20 GB GDDR6, 7.1x the memory bandwidth on the H800, and NVLink 400 GB/s on the H800 where the RTX 4000 SFF Ada is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.

| On-demand | No on-demand listings | -- /GPU/hr from $0.43 |
Heads up: A provider's own page may quote a different figure, for example on tax, region or a promotion. A monthly-only plan shows a derived hourly rate. Medians are across providers, one vote each, so a large catalog does not outweigh a small one. No median for on-demand on the RTX 4000 SFF Ada: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
